I'm done with this one. Okay so to sum up a little bit for those who will come after. Things to be very careful with : - Scale : When you export in 3dsmax, or in Blender make sure you keep the same scale. Otherwise, you won't see the props in game without looking really close to the ground. - Pivots : When switching from 3dsmax to blender you may notice that the links are not in the middle, that's because the pivot point in max was not in 0,0,0. - Links : All the dummies you use for props should be carefully children of the main object. In blender this is just drag and drop, and in max you will use the buttons to link them. Select all except the parent with you mouse and draw a link to the parent. You will see as much links as dummies, drop the link when you are on the parent. - Rotations : Be careful with rotations. In 3dsmax Z axis is height, while in the game it's Y. - Exportations : Make sure when you export a prop that you are not exporting the whole mesh, that may sound stupid, but since the game does not support multimesh you will get an error. Also, center your prop. Otherwise you will also get the offset. Theatron_Proped.7z
